Definitions

  • the system includes a controller operatively coupled to the chlorinator and the pump.
  • the controller accepts settings from a user for the pump operation time setting and the chlorine output setting and the controller is programmed to automatically control the chlorinator and the pump based on a relationship between the chlorine output setting, a chlorine generation capacity of the chlorinator, and the pump operation time setting.
  • exemplary embodiments can advantageously account for the impact of the filter schedule (e.g., the pump operation time per day). This allows for the display and settings of the chlorinator to accurately reflect the levels of chlorine actually being delivered to the body of water.
  • the filter schedule e.g., the pump operation time per day.
  • exemplary embodiments of the present disclosure can simultaneously (or on a priority basis) change the chlorine feed rate and/or the filter schedule to achieve the requested chlorine output levels.
  • FIG. 1 is a block diagram of an exemplary system 2 for sanitizing, filtering, and circulating water 3 contained in a body of water 4 (e.g., a pool or spa).
  • the system can include a pump 6 (e.g., a variable speed pump) having an associated pump controller 8 , a chlorinator 10 including a replaceable chlorinator cartridge 60 , which is discussed in more detail below, a main system controller 15 , and a chlorinator controller 20 .
  • the pump 6 can be a filter pump associated with a filter (e.g., a sand filter) (not shown) that filters debris and contaminates from the water 3 .
  • a filter e.g., a sand filter
  • the chlorinator controller 20 can be communicatively coupled to the chlorinator 10 , as shown by line 5 , and can be communicatively coupled to the pump controller 8 , as shown by line 7 .
  • the system controller 15 can be communicatively coupled to the chlorinator 10 , as shown by line 9 , the pump controller 8 , as shown by line 11 , and the chlorinator controller 20 , as shown by line 13 .
  • FIG. 2 is a perspective view of a controller 10 and a chlorinator 20 of the present disclosure, interconnected by a cable 30 .
  • the chlorinator 10 includes a casing 12 , a transparent or translucent body 14 , a screw cap 17 , a first compression nut 18 a , and a second compression nut 18 b .
  • the nuts 18 a , 18 b permit connection of a first pipe 19 a and a second pipe 19 b (such pipes forming part of the overall piping of a pool/spa equipment installation) to the chlorinator 10 .
  • the body 14 a houses a chlorinator cartridge (or cell, both terms being used interchangeably herein) 60 (see FIG. 6 ), discussed in greater detail below.
  • the standing by light 42 d indicates that the chlorinator 10 is not operating but is in normal condition.
  • the generating chlorine light 42 e is illuminated by the controller 20 when the chlorinator 10 is generating chlorine.
  • the super chlorinating light 42 f is illuminated when the chlorinator is generating elevated levels of chlorine for a short period of time (e.g., to quickly boost the level of chlorine in a pool or spa).
  • a plurality of membrane switches 46 a - 46 c are provided for controlling the chlorine output level—by pressing the switch 46 a , the user can decrease the level of chlorine generated by the chlorinator 10 (causing fewer of the lights 44 a - 44 j to illuminate). Conversely, by pressing the switch 46 b , the user can increase the level of chlorine generated by the chlorinator 10 (causing a greater number of the lights 44 a - 44 j to illuminate).
  • a chlorine feed rate of the chlorinator 10 and/or a pump operation time of the pump 6 can be programmatically adjusted in response an increase or decrease in the chlorine output setting.
  • step 118 occurs, wherein the controller 20 enters an error state and operation of the cell 60 is not permitted. Otherwise, if the cell 60 is authenticated, step 120 occurs, wherein the controller 20 determines the type of the cell 60 . For example, by communicating with the cell 60 , the controller could determine whether the cell 60 is an extended-life cell or a cell having a reduced lifetime.
  • step 122 once the cell type has been determined, the controller 20 executes a calibration process for calibrating operation of the cell 60 . To do so, in step 124 , the controller 20 reads one or more parameters from the cell 60 . It is noted that the cell 60 could be authenticated upon the first communication between the controller 20 and the cell 60 after system power-up, periodically, or every time a communication occurs between the controller 20 and the cell 60 .
  • the chlorinator 10 can be initially set to a daily chlorine output of forty percent (40%), a feed rate of eighty percent (80%) (based on a three hour operation cycle), and a daily pump operation time of twelve hours (12 hrs).
  • a user can increase the chlorine output setting to fifty percent (50%), and the controller 20 can be programmed to respond by increasing the chlorine feed rate to one-hundred percent (100%), while the pump operation time remains unchanged. Subsequently, the user can increase the chlorine output setting to sixty percent (60%).
  • FIG. 17 is a diagram illustrating a system according to the present disclosure, indicated generally at 250 , for remotely diagnosing errors and/or malfunctions associated with pool/spa equipment.
  • the system 250 includes a diagnostic server 252 which executes a diagnostic software engine 254 , in communication with a local application executing on a computer system 258 .
  • Communication could be by way of the Internet 256 , a local area network (LAN), a wide area network (WAN), a cellular network, etc.
  • the computer system 258 could be a personal computer, tablet computer, cellular phone, smart phone, etc., and the local application executed by the computer system 258 generates a diagnostic graphical user interface (GUI) display 260 that is displayed on a display of the computer system 258 .
  • GUI diagnostic graphical user interface
  • the local computer system 258 could also include a microphone 262 and a camera 264 , both or either of which could be used to obtain information about the malfunctioning equipment 266 .
  • the user could record the sound using the microphone 262 and transmit the recorded sound to the diagnostic server 252 using the local application, whereupon the recorded sound is processed by the software engine 254 (e.g., the recorded sound is compared to a database of sounds made by pumps which are indicative of various conditions) and a solution to the problem is generated and transmitted back to the local computer system 258 for display to the user.
  • the functionality of the diagnostic software engine 254 could be provided within the application executing on the local computer system 258 .
  • the GUI 260 could include a three-dimensional model of the user's pool/spa, and the user could re-create the present configuration of the pool/spa and condition of associated equipment using the model. For example, the user can “drag-and-drop” representations of items such as a pool skimmer, main drain, lights, stairs, and other pool features into the model.
  • an algorithm executing locally on the local computer system 258 , or remotely on the diagnostic server 252 ) can analyze the model and recommend a specific manner in which to operate pool/spa equipment in order to obtain better results (e.g., it could recommend better ways of operating a pool/spa cleaner (or of programming same) based upon the model created by the user). Further, the algorithm could produce a new cleaning program based upon the model, which could be downloaded to a robotic pool cleaner (e.g., via USB, wirelessly, etc.).
